a source of sound produces 20 compressions and 20 rarefractions in 0.2 seconds.the distance between a compression and rarefaction is 50cm . find the wavelength,frequency and time period of the wave.
please do answer it fast cuz tommorow is my finals.
Wavelength- It is the distance between a compression and an adjacent rarefraction.so Wavelength is 50cm.
Frequency = Frequency of a wave is the no. of waves produced in 1 second.
So frequency = 20/0.2
Time period = The time required to produce one complete wave is called time-period od the wave.
Frequency = 1/time period
100 = 1/time period
100 time period = 1
Time period = 1/100
